The MS40 is a pair of ceiling speakers with tough, water-resistant, plastic housing. Supplied with cable, the speakers are extremely easy to install and connect to an amplifier. The two-way coaxial system design provides great low-mid frequencies from its 4-inch woofer driver, as well as clear high-end sound reproduction. Ideal for use in kitchens, bathrooms, and any other room due to the water-resistant IP rating, provided by the one-piece, sealed plastic housing design. The installation has been made as easy as possible, with clear and concise instructions on how to do so. Choose a location, measure and cut a hole to size, connect the cables, and screw into place. These speakers with 4-inch drivers run with 15 watts of continuous RMS power output supplied at 8 Ohms via a required matching amplifier.
